CONDENSATE AND AIR REMOVING APPARATUS.

Original application illed December 30, 1916, Serial Nc` 139,985. Divided and this application tiled January` Serial No. 210,654.

To all 'whom it ma concern.;

Be it known that I, ROBERT SUGZEK, a subject of the Emperor of A11striaHunga1'y, residing in the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Iluprovements in Condensate and Air Removing'Apparatus, of which the following is a specification.

My invention relates to apparatusfor removlngcodensate and air from either: a surface condenser or jet condenser, or km- 'dred apparatus, or in general relates to pumping apparatusfor simultaneously operating upon-liquid and gas.

My lnvention resides inl apparatus of the character referred to com rising centrifugal pumping apparatus em dying impellcr structure w ereby the liquld 1s` operated upon centrifugally a plurality of times in succession, means being 'provided for delivering the air or gas into-the lmpeller structure into thel'iquid after it ,has been acted upon centrifugally and before 1t 1s finally so operated upon,vacceler at1ng nozzle structure also being provided 4if ldesired for forcing the air or gas into 'tlleliqiful My invention iresides in apparatus of the character hereinafter described and claimed.

For an illlilstration of some of the various forms myiifnvention may take, reference is had to the accompanying drawlng, in which:

Figure 1l `is a sectional view, some partsin elevation, f apparatusembodymg my 1nvention.

Fig. 2 is a sectional view, some parts 1n elevation, of a. modification of the structure shown in Fig. 1.

Referring to Fig. 1 C represents a surface condenser for condensing steam or vapor, especially the exhaust steam from a steam power, plant or the like. The condensed steam or condensate is delivered through the opening 2 into the passage 3, which delivers to the suction of the centrifugal pump structuyc P, the latter comprising the usual volute 'nr discharge casing 4 and the submerged impeller structure comprising the impeller I of'larger diameter having vanes V and the second impeller of smaller diamA eter I, having the vanes V, the impellcr structure being rotated at high speed by Specification of Letters *Patent impeller structure.

'of the circumfercntially spaced ribs 16 resembling the spokes of a wheel. v l

A n air connection 9 communicates with the interior of the condenser C and with the suction chamber of the ejector,E,"of an Isuitable type, to which'elastic motive Hui as steam, is delivered, Ithe steam emitted from the ejector nozzle entraining in the well known manner the air or uncondensabl'e vapors delivered from Vthe condenser C through the pi e 9, the mixture being then so'v delivered to t e second stage ejector El which delivers at 17 into the dividedpassages or connections 18, 18 communicating with the annular chambers 19 on opposite sides of the impeller structure.l Pipes 20, delivering preferably llve steam from any suitable source, communicate with the annularchambers 21 on opposite sides of the On eachside of the impeller structure, 'with .suitable circumferential spacing, is provided a series of steam expanding nozzles 22 receiving steam from the annular chambers 21 and delivering the same at high vclocitv across the chambers 19 and through the spaces between the ribs 16 into the space between the inner and outer impellers I, and I.

` In operation, the water or condensa-te delivered through the passage 3 into the suction 6 is operated upon centrifugally by the inner impeller I, and delivered by it at its periphery radially outwardly to the outer lmpeller I from which it is discharged into thevolute or discharge casing 3, from which it'is then delivered to any suitable point at` any suitable pressure, generally atmospheric pressure. The water is thus acted upon in successive stages, each increasing its pressure. The water in its assage through the impeller structure is .clivered from the periphery of the impeller I, into the free space between that impcller and the inner edges of the vanes V of the mpeller I. The impeller I, may preferably be so constructed that it preliminar-ily accclarates the condensate without materially increasing itsv For this purpose it will *suifice` pressure.

if the impeller I1 by centrifugal action pro- 5 duces a pressure sufficient to prevent air or vapors from the condenser passing through the impeller I1 from its periphery toits suction into the condensate and from there back into 'the condenser shell through passages 3 and 2.

Simultaneously with the flow of the condensate through the impeller structure as described, the ejector or other air removing apparatus removes air and uncondensable vapors, from the condenser and delivers them'through the passages 18, 18 to the annularcharnbers 19 where steam from the nozzles 22 carries the mixture of steam and air from thev pipes 18 into-'the space between A the impellers ,L and I, where the mixture enters the 'liquid or livered thereby into atmospheric pressure.

as t0 in' effect vconstitute vanes which assist in the movement ofthe vapor and air intoy the liquidI or condensate.
